Struct opencv::bgsegm::BackgroundSubtractorCNT

pub struct BackgroundSubtractorCNT { /* private fields */ }

Background subtraction based on counting.

About as fast as MOG2 on a high end system. More than twice faster than MOG2 on cheap hardware (benchmarked on Raspberry Pi3).

Trait Implementations

impl AlgorithmTrait for BackgroundSubtractorCNT

fn as_raw_mut_Algorithm(&mut self) -> *mut c_void

fn clear(&mut self) -> Result<()>

Clears the algorithm state

fn read(&mut self, fn_: &impl FileNodeTraitConst) -> Result<()>

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for BackgroundSubtractorCNT

fn as_raw_Algorithm(&self) -> *const c_void

fn write(&self, fs: &mut impl FileStorageTrait) -> Result<()>

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &mut impl FileStorageTrait, name: &str) -> Result<()>

Stores algorithm parameters in a file storage

fn write_with_name(&self, fs: &Ptr<FileStorage>, name: &str) -> Result<()>

@deprecated

fn write_with_name_def(&self, fs: &Ptr<FileStorage>) -> Result<()>

👎Deprecated:

Note

Deprecated: ## Note This alternative version of AlgorithmTraitConst::write_with_name function uses the following default values for its arguments:

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

impl BackgroundSubtractorCNTTrait for BackgroundSubtractorCNT

fn as_raw_mut_BackgroundSubtractorCNT(&mut self) -> *mut c_void

fn apply( &mut self, image: &impl ToInputArray, fgmask: &mut impl ToOutputArray, learning_rate: f64 ) -> Result<()>

C++ default parameters

fn apply_def( &mut self, image: &impl ToInputArray, fgmask: &mut impl ToOutputArray ) -> Result<()>

Note

fn set_min_pixel_stability(&mut self, value: i32) -> Result<()>

Sets the number of frames with same pixel color to consider stable.

fn set_max_pixel_stability(&mut self, value: i32) -> Result<()>

Sets the maximum allowed credit for a pixel in history.

fn set_use_history(&mut self, value: bool) -> Result<()>

Sets if we’re giving a pixel credit for being stable for a long time.

fn set_is_parallel(&mut self, value: bool) -> Result<()>

Sets if we’re parallelizing the algorithm.
